Abstract: Construction 3D printing, although a technology that is expected to provide cost, speed and environmental benefits as compared to the traditional construction practices, suffers from inefficient and often troublesome material delivery by pumping cementitious material through hoses or pipes. The present application addresses the need for a consistent and discrete payload delivery between a source and a moving destination. The invention describes an aerial tram delivery system that provides real-time, on-demand, and discrete transportation of material from a material source to the moving destination printheads of the construction 3D printer. Such discrete delivery of material is applicable and beneficial to other applications as described.
